The important attribute involved is border-radius; through this attribute, the image can be rounded.

The functions of the properties of border-radius are as follows:

border-radius: 2em, which means that all four corners are rounded, and the radius of each rounded corner is 2em.

You can set two values, such as border-radius:2em2em; the first value represents the upper left rounded corner and the lower right rounded corner, and the second value represents the upper right rounded corner and the lower left rounded corner.

Set 3 values, such as border-radius: 2em 2em 2em; the first value indicates the upper left rounded corner, the second value indicates the upper right and lower left rounded corners, and the third value indicates the lower right rounded corner.

Set 4 values, such as border-radius: 2em 2em 2em2em; the 4 values represent upper left, upper right, lower right, and lower left respectively.

You can also split the 4 corners into 4 separate attributes to set, such as upper left corner (border-top-left-radius), upper right corner (border-top-right-radius), lower right corner (border-bottom-right-radius) and lower left corner (border-bottom-left-radius).
